The connector complies with the requirements of UIC 558 VE (until 1994: UIC 568VE). It connects lines used for remote control of lights and doors or for public address systems in passenger coaches or multiple unit trains. In addition to that, the connectors of this series are also suitable for trans­mission of binary data, e.g. CAN bus.

Schaltbau has developed a new replacement insert for the recept­acle of the UIC558 con­nector which is likely to re­duce main­tenance and downtime consider­ably. For usually, if during main­tenance it becomes necessary to replace worn contacts, you have to cut the old cable in order to replace the insert and after that wire a new cable to it or, in the worst case, rewire the whole railway vehicle. Now, there is no need of a cable replace­ment any longer. All you need do is exchange the replace­ment insert of the receptacle. You can do that from the front and outside the engine shed and even do without the electrical test of the connector’s contacts and wires.
